ST. LOUIS, MISSOURI` DOOR FOR STOVE-OVENS.

SPECIFICATION forming part of Letters Patent No. 246,606, dated September 6, 1881.

Application tiled January 24, 1881.

To all whom it may concern Beit known that I, GILES F. FILLEY, of St. Louis, Missouri, have made a new and useful Improvement in Doors for Cooking Stoves and Ranges, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making partof this specication, in which- Figure l is a side elevation ofacookingstove or range oven door having the improvement, and Fig. 2 a vertical transverse section thereof'.

The same letters denote the same parts.

I have heretofore made an improvement in cooking stoves and ranges the aim and effect of which is to cause the outer air to pass directly into and to circulate through the oven wherein the articles are being` cooked, and

thence out therefrom.

Thepresent invention is mainly an improved means for admitting the outer airdirectlyinto and discharging it lrom the oven; and it consists in providing the door or doors of a stove or range oven with a register of such size and so arranged that the outer air can pass through d the lower openings ofthe register into the lower part of the oven and be discharged through the upper openings of the register from the ripper' part ot' the oven.

The invention is carried out by insertingin the oven door or doors a register' which nearly or quite fills the main portion of the door, as in the drawings, wherein- A represents a door of a cooking stove or range oven, and which, saving as modified by the present improvement, may be of the usual construction.

B represents theregister in question, extending, as seen, throughout the main portieri a of the door. The register is preferably made to open more in iis upper halt' than in its lower halt'. This may be eifected by making the register-openings b b of uniform size, but more in number in the upper portion of the register, as shown in Fig. l.

In operation the air enters the oven through thelower openin gs and leaves the oven through (No model.)

| the upper openings ofthe register, as indicated by the arrows.

The register can be opened more or less widely, according to the amount ot' air it is desired to have pass through the oven.

Fine gauze or tinely-pert'orated metal C may be used in connection with the register, both to subdivide the hea/t and air currents and as aguard. The gauze may be fixed in position opposite the registeeopenings by any suitable means.

In Fig. 2, F represents t-he oven-top, E the side plate of the stove or range, and G the oven-bottom.

In place of a rotating register, C, such as shown, a slide-register may be used.

If desired, a small register, D, may be iuserted in the part a ot the door.

I am aware that an oven-doorhas had a small registerinserted in the centerof the door. Such register, however, did not extend throughout, or evennearly throughout, the main portion ot' the door, and it could not be used to promote an air-circulation in the manner contemlilated by the present improvement.

l. A cooking stove or range oven door or doors having a register arranged and extended throughout the main portion of the door, as and for the purpose set forth.

2. A cooking stove or range oven door or doors having the registerB and gauze C, said register being arranged and extended as and for the purpose set forth.

3. The combination of the door A and register B, said register having a larger opening in its ripper than. in its lower halt', substantialiy as described.

4. A cooking stove or range oven door or doors having a register, B, arranged and excombination.
